I was instantly approved for $2,000 with both CK scores being 723 and a "Good" chance of approval. Capital One pulled my Experian FICO score which was at that time 732 with 4 inquiries and no bad history/collections. My income is under $20,000 and I am a student with 4yrs being my oldest credit line. I have 4 credit cards (one being another Cap 1 card, the Quicksilver with a CL of $500), 2 store cards and 2 student loans listed. I'm not sure if it really made a difference but I signed up for Sony Rewards first and applied thru their website not CK.
This is an excellent card for what is it which is a very narrow category rewards card. This card is best for people who own a PlayStation and who buy off of the PSN store regularly. Since it has no annual fee there is no reason to worry if you don't use the card every month but I highly recommend making this the card linked with your PSN account and using it only for PlayStation related purchases. You can also get points back for dining out and paying your cell phone bill via the card. However, there are better cards for the dining out option such as the Marvel MasterCard with its 3% back on dining/entertainment categories.
As it is a Visa you can use it anywhere Visa is accepted but I applied for and now use this card solely for the PlayStation aspect. I linked the card to my PSN and Sony Reward accounts and use it for PSN store purchases and nothing else.
